[0025] The L-shaped base 1 can be mass-produced, thereby reducing the production cycle and improving delivery efficiency.

[0026] In this embodiment, a pair of L-shaped fixing grooves 8 are opened on the opposite sides of the support column 5, and the L-shaped fixing grooves 8 are movably connected to the limit blocks 9 on the tube panel structure 6. The limit blocks 9 are fixedly installed on both sides of the fins 10, and the water-cooled wall tubes 11 are embedded and fixedly installed on the fins 10.

[0027] The limiting block 9 moves along the L-shaped fixing groove 8 to achieve the limiting installation of the tube panel structure 6 .

An annular groove is opened on the inner side wall of the end of the first connecting head 12 and a sealing ring 16 is fixedly installed. A sealing block 17 is slidably connected to the inner wall of the second connecting head 13, and a second spring 18 is fixedly connected between the end of the sealing block 17 and the side wall of the second connecting head 13.

The T-shaped stopper 15 squeezes the sealing block 17, and at the same time, the second connecting head 13 squeezes the L-shaped sealing sleeve 14 to achieve the connection between the first connecting head 12 and the second connecting head 13.

[0031] In this embodiment, the first connecting mechanism 4 includes a first connecting tube 19 fixedly installed on the side wall of the L-shaped base 1, a third spring 20 is fixedly installed at the bottom of the first connecting tube 19, a blind hole is opened on the inner wall of the first connecting tube 19 and a fourth spring 21 is fixedly installed, the end of the fourth spring 21 is fixedly connected to the first clamping block 22, a through hole is opened between the first connecting tube 19 and the pipeline 3 and a piston 23 is slidably connected, and the top of the piston 23 is fixedly connected to the second clamping block 24 through a connecting rod.

[0032] The third spring 20 is used to eject the first cone block 25, and the fourth spring 21 is used to reset the first clamping block 22. When the internal pressure of the pipeline 3 changes, the piston 23 will be driven to move, thereby driving the second clamping block 24 to move.

[0033] In this embodiment, the first clamping block 22 is engaged with the first cone block 25, and the second clamping block 24 is engaged with the second cone block 26. The bottom diameter of the first cone block 25 is slightly smaller than that of the second cone block 26. The first cone block 25 is fixedly installed at the end of the slide rod 27. The middle part of the second cone block 26 passes through and is slidably connected to the slide rod 27. A fifth spring 28 is fixedly connected between the first cone block 25 and the second cone block 26. A thick rod 29 is fixedly installed at the front end of the slide rod 27. A threaded hole is opened inside the thick rod 29 and is threadedly connected to a screw rod 30. The screw rod 30 is rotatably installed inside the second connecting tube 31 through a bearing. The second connecting tube 31 is fixedly installed on the side wall of the long base 2. A worm wheel 32 is fixedly installed at the end of the screw rod 30. The worm wheel 32 meshes with the worm 33. The worm 33 passes through the second connecting tube 31 and is fixedly installed on the turntable 34.

[0034] Among them, the fifth spring 28 is used to reset the second cone block 26, and the rotating turntable 34 drives the screw rod 30 to rotate through the engagement of the worm wheel 32 and the worm 33. The rotation of the screw rod 30 drives the thick rod 29 to move, thereby driving the first cone block 25 and the second cone block 26 on the slide rod 27 to move.

[0035] In specific application, firstly, the corresponding L-shaped base 1 and the long base 2 are arranged according to the size, so that the first connecting tube 19 is aligned with the second connecting tube 31, and the turntable 34 is manually rotated to drive the screw rod 30 to rotate through the meshing of the worm wheel 32 and the worm 33. The rotation of the screw rod 30 drives the thick rod 29 to move, thereby driving the first cone block 25 on the slide bar 27 to squeeze the third spring 20 and engage with the first clamping block 22, thereby forming a complete base frame, and the support column 5 is fixed to the L-shaped base 1 by bolts, and then the limit blocks 9 on both sides of the fin 10 are aligned with the L-shaped fixing groove 8 and slide into it. When the water-cooled wall tube 11 falls, the first connector 12 is automatically sleeved on the second connector 13, and the T-shaped stopper 15 in the first connector 12 squeezes the sealing block 17, and at the same time, the side wall of the second joint 13 squeezes the L-shaped sealing sleeve 14, so as to realize the first connection The first connecting head 12 and the second connecting head 13 are connected. When it is necessary to disassemble the tube panel structure 6, the tube panel structure 6 is lifted upward. At this time, the first connecting head 12 and the second connecting head 13 are automatically disengaged, and then the limit block 9 can slide out along the L-shaped fixing groove 8. When the base frame is disassembled, it is necessary to stop injecting cooling water into the pipeline 3. Then the pressure in the pipeline 3 decreases, and the piston 23 drives the second clamping block 24 to move downward to disengage it from the engaged second cone block 26. The turntable 34 is manually rotated again, so that the first cone block 25 continues to compress the third spring 20. At the same time, the thick rod 29 drives the second cone block 26 to squeeze the first clamping block 22. When the bottom of the second cone block 26 passes over the first clamping block 22, the third spring 20 pops the first cone block 25 out of the first connecting tube 19, so that the first connecting tube 19 is separated from the second connecting tube 31, thereby completing the disassembly operation.
